Hi I can't post a vid because I have already made it but I can tell you how I went about it.
first I bought some hardwood strips from ebay (used for dolls houses etc) 25mm wide by 2.5mm thick. One of these needs about 2mm off the edge so it's 23mm wide and then glue together with wood glue and clamp - this gives the recess for the side panels. You will then need to cut 45 degree mitre joints after you decide how big you want the box, I used 80mm high by 50mm wide. before you glue the cut sides together drill the holes for the 510 and button and then glue I held the 4 sides with elastic bands. For the sides I used stainless steel (you can get magnetic sheets on EBay), you could use copper brass or wood but would then need to glue on magnets to the panel as well as the wooden box. The copper strip is held at the bottom by 2 small screws.
Parts - Modmaker 510, ss button, magnets and bottle.
EBay - Hardwood strips, stainless steel sheet and copper strip (used for roofing)
Amazon - Woodglue
You don't need a lot of tools but a vice, clamps, drill, metal files, mitre saw and Dremel are what I needed. I finished it off with a fine sandpaper and treated it with furniture oil rather than varnish.
I hope this helps.
